Example: Configuring an Ordinary Slave Clock Without Unicast-Negotiation
This example shows the base configuration of a Precision Time Protocol (PTP) ordinary
slave clock without unicast-negotiation on an ACX Series router.
NOTE: ACX5048 and ACX5096 routers do not support ordinary clock.

Requirements
This example uses the following hardware and software components:
NOTE: This example also applies to QFX Series switches. QFX Series switches
do not support Gigabit Ethernet interfaces. Instead, configure PTP boundary
clock parameters on 10-Gigabit Ethernet interfaces.
•
One ACX Series router
•
Junos OS Release 12.2 or later
Overview
In this configuration, unicast-negotiation is not configured, so the PTP slave has no control
over the rate of the negotiation. The PTP master (a Brilliant Grand Master or an MX Series
router) must be configured with the parameters of the PTP slave, such as announce,
synchronization, and delay-response packets to control the rate of the negotiation.
NOTE: The values in this example are for illustration purposes only. You can
set the values for each parameter according to your requirements.
Configuration
To configure an ordinary slave clock without unicast-negotiation, perform these tasks:
NOTE: The ipv4-dscp statement is not supported on the QFX10002 switch.
